Abstract：Objective To explore a new method for the repair of auricle anterolateral aspect defect.Methods Prior to surgery,Doppler ultrasound blood flow detector was used to mark the location of the pretragal perforator vessel.Pretragal artery perforator pedicled flaps were designed with the following considerations:defect area,distance from the wound distal to the antilobium,and degree of laxity of the auricle skin.The distal flap was incised,separated from the distal to the proximal,andclose to the superficial layer of the SMAS fascia,and the perforator pedicled flap was formed.The flap was transferred and the defect was covered.The donor site was closed and sutured direcdy.Results All flaps survived well and healed primarily.Follow-up was performed from 6 to 12 months postoperative.No swelling,obvious scars,or facial malformation occurred.All patients felt satisfied with the appearance and functional results.Conclusion The pretragal perforator island flap has the following advantages:simple design,rich blood supply,convenient operation,and hidden donor incision.It is feasible for promotion in clinical application.
